'UNIVERSAL LUBRICATING DEVTCE.

. Application led January 29, 1921.

To all whom t may concern.'

Be it known that I, C ARL GUGGENBUEH- LER, a citizen of Germany, residing at New. ark, in the county of Essex and State of New Jersey, have invented certain new and useful lmprovernents'in Universal Lubricating Devices, of which the following is a specification.

The present invention relates to lubricating devices, and constitutes an improvement of the invention described and shown in my co-pending application Serial #348,313, filed December 30th, 1919,.,and of which the present application is a continuation.r

The object of the invention is to sol construct the lubricating device that both the discharge controllingv valve and the lubricant feed will be automatically controlled from a lcommon means controllingr the operation of the vehicle.

Another object of this invention is to provide a positively operated lubricant feeding means which will be automatically operated at aforedetermined times, but not continu-v ously, whereby waste of lubricating material will be obviated.

My invention will be fully understood by reference to the accompanying drawing in which similar characters denote corresponding parts and in which Fig. 1 is a side elevation of my -device shown as applied to amotor vehicle; Fig. 2 is an enlarged vertical sectionl of the device proper on line 2 2 of Fig. 1. Fig. 3 is a reduced top plan view of the device and Fig. 4 a reduced cross section on line 4-4 of Fig. 2.

10 denotes the vehicle of which 11 is the motor casing and 12 the means for controlling the operation of the vehicle, such as emergency brake controlling lever. The lubricating device L may be arranged at a suitable place withinthe casing 11 and may comprise a double container 13, 14 for grease and oil or the like.

As the present improvement merely deals withthe construction of the plunger working in the central container 13 and the mode of feeding said plunger while operating the valve controlling the discharge openings of said central container, it will be unnecessary to describe the details of or refer hereafter to the second container 14; and the individual valves controlling the discharge openings of the latter. Moreover, the device is not liniited to double containers, but may be con- Serial No. 440,840.

structed with one cylinder to Contain only one kind of lubricant.

The v,bottom of this container 13 is closed by'a'cap shaped bottom 15 having a plurality of discharge openings 16 which are con- 60 trolled by a rotary valve 17 mounted in said bottom"substantially as in the aforenamed co-pending application, and having openings 18 whichy are arranged, sized and spaced 1n conformity withthe openings 16. 6 5

Arranged in the container 13 is a longiv'tudinally movable plunger 19 for feeding the lubricant. This plunger is guided so that it will not becapable of turning and to this end it may be provided. with diametri` 7@ cally opposed projections. 2() engaging longitudinal'gui'degrooves 13 formed 1n the i inner wall of the container 13. The stem or rod 21 ofsaid plunger is adapted to extend through a central opening 22 provided in 75 thel top 23 of the container. Said rod is provided with a central bore 21 extending longitudinally throughout` the length thereof and serving as charge opening for the grease or other lubricant.

This charge opening is normally closed by a plug 25 extending through the said bore and screwing with its lower threaded end 25 in the lower threaded part of the bore 21.

The outer circumference of the stem is $55 provided with fine thread 212 and adapted to work in a correspondingly threaded nut 26 mounted in the central opening 22 of the top 23, to be capable of rotary but not longitudinal movement. Fixed to or formed inte- W@ graly with the nut 26 isla ratchet wheel 27 whereby intermittent rotary motion can be imparted to said nut, by the rotation of which the plunger 19 vthrough'its stem 21 will be moved to feed the lubricant. te

(lo-operating with said ratchet wheel is a spring actuated pawl '28 pivoted at 28 in an arm 29 which is fulcrumed at 29 to the top 23 of the container.

This arm 29 extends parallel to the arm 30 to@ fixed to and projecting from the valve 17 and is operatively connected thereto by a vertical rod 31. v

The member 12 which in the present eX- ample is shown as brake operating lever, but which may be any other means for controlling the operation of the vehicle, has connected to it a bar 32 to whichis pivoted one end of a double armed lever 33 fulcrumed at 34 to a stationary part 35 of the vehicle. The 110 Whenever it is desired to feed the llubricant to different parts of the machine, either when the 'machine is started and the emergenc released or some other member controlling the operation of the machine is operated, the particular member such as the lever 12 when moved transmits movement to the `valve 17 through the medium of the arm 32, lever 33 and link 36. Simultaneously, the rod 31 is moved in circular direction with the arm 32, and the] upper end of said rod slides from one end of the loop 292 towards the opposite end and when reaching the latter carries the arm 29 along with it. The arm 29 receives thereby a rotary motion around its fulcrum 29 as a result-of .which its pawl 28 will turn the nut 26 through the medium of the ratchet 27 and cause the plunger 19 to vslightly move inwardly feeding the lubricant through the opened discharge openings.

The nut 26 may be provided with means for its operation by hand, so as to permit the turning of the nut in opposite direction and thereby move the plunger back to its initial position after the contents of the container ,have been used up and the latter is to be refilled.V Such means may consist of thumb members 37 or the like.

The plug 25 may have-its outer end formed to a square 25- or other suitable means for engagement of a proper tool whereby it may be readily manipulated.

Itis obvious that the device can be variously modified without departing fromv of a lubricant container having discharge openings, a valve for controllin said discharge openings, a plunger for ceding the lubricant, said plunger having a threaded stem, a nut for said stem held against longitudinal movement, a ratchet wheel connected to said nut, a pawl co-operatingwith tively connectedk to said valve and common means for moving said valve and arm, said means .being controlled from said first named means.

ln testimony whereof` I aflx my signature in presence of two witnesses.
